Q.I want to use my MIDI keyboard to play a software synthesizer in realtime. How much latency should I expect?

A.The latency that occurs when playing in realtime will depend on the available audio buffer size that can be specified for your host application and audio driver.
Note that the available audio buffer size will also depend on the performance of the PC and audio device you are using.

If you are using a high-speed audio device that supports WDM or ASIO, you will get minimal latency in performance, which will allow you to play the synth in real time without hearing an audible delay between the time you strike the key and the time the audio starts playing.
